Display Device Comprising a Touch Sensor Formed Along a Perimeter of a Transparent Region That Extends Through a Display Layer and Exposes a Light Sensor

1. A system comprising: a substantially transparent cover layer defining an outside surface associated with a display showing an image; a display layer disposed beneath the substantially transparent cover layer, the display layer comprising a display substrate and a plurality of display elements disposed on the display substrate, the plurality of display elements configured to transmit light; a light sensor disposed beneath the substantially transparent cover layer and proximate to the display layer; wherein a substantially transparent region extends through the display layer, and faces and exposes the light sensor, the substantially transparent region interrupting the image shown on the display; and a touch sensor formed along a perimeter of the substantially transparent region and defining a second substantially transparent region associated with a touch sensor layer, wherein the second substantially transparent region has a smaller area than an area of the substantially transparent region, and wherein the touch sensor activates the light sensor when the touch sensor is activated.

2. The system of claim 1 , the substantially transparent region having a rectangular shape with at least two rounded corners and disposed along an edge of the display.

3. The system of claim 1 , the substantially transparent region having a U-shape and disposed along an edge of the display.

4. The system of claim 1 , wherein the second substantially transparent region is smaller than the substantially transparent region, and wherein the touch sensor activates the light sensor when the touch sensor is activated.

5. The system of claim 4 , comprising the second substantially transparent region concentric with the substantially transparent region, and wherein an area comprising a difference between the substantially transparent region and the second substantially transparent region comprises the touch sensor.

6. The system of claim 1 , comprising a color filter (CF) layer disposed beneath the substantially transparent cover layer, the CF layer comprising a CF substrate and a plurality of color regions disposed on the CF substrate, the CF layer to provide color to the display, wherein the substantially transparent region extends through the CF layer.

7. The system of claim 1 , comprising an activating layer disposed beneath the substantially transparent cover layer, the activating layer to cause a display element in the plurality of display elements to transmit light, wherein the substantially transparent region extends through the activating layer.

8. The system of claim 7 , the activating layer comprising a thin film transistor (TFT) including a TFT substrate and a plurality of TFTs disposed on the TFT substrate.

9. The display of claim 1 , the display layer comprising an organic light emitting diode (OLED) layer disposed beneath the substantially transparent cover layer, the OLED layer comprising an OLED substrate and a plurality of OLEDs disposed on the OLED substrate.

10. The display of claim 1 , the display layer comprising a liquid crystal display (LCD) layer including an LCD substrate and a plurality of liquid crystals disposed on the LCD substrate.

11. The display of claim 1 , the light sensor comprising at least one of a camera or an infrared (IR) sensor.

12. The display of claim 1 , further comprising a plurality of lenses including at least one of: a cover layer lens disposed on the substantially transparent cover layer; or a display layer lens disposed on the display substrate.

13. The display of claim 1 , wherein the light sensor represents a light sensor icon associated with the display.

14. The display of claim 1 , wherein the substantially transparent region is a hole.

15. A method comprising: configuring a substantially transparent cover layer to define an outside surface associated with a display showing an image; configuring a display layer disposed beneath the substantially transparent cover layer, the display layer comprising a display substrate and a plurality of display elements disposed on the display substrate, the plurality of display elements configured to transmit light; configuring a light sensor disposed beneath the substantially transparent cover layer and proximate to the display layer; extending a substantially transparent region through the display layer, and faces and exposes the light sensor, the substantially transparent region interrupting the image shown on the display; and forming a touch sensor along a perimeter of the substantially transparent region and defining a second substantially transparent region associated with a touch sensor layer, wherein the second substantially transparent region has a smaller area than an area of the substantially transparent region, and wherein the touch sensor activates the light sensor when the touch sensor is activated.

16. The method of claim 15 , comprising: shaping the substantially transparent region into a rectangular shape with at least two rounded corners; and disposing the substantially transparent region along an edge of the display.

17. The method of claim 15 , comprising: shaping the substantially transparent region into a U-shape; and disposing the substantially transparent region along an edge of the display.

18. The method of claim 15 , comprising: defining the second substantially transparent region smaller than the substantially transparent region, wherein the touch sensor activates the light sensor when the touch sensor is activated.

19. The method of claim 18 , comprising: defining the second substantially transparent region concentric with the substantially transparent region, wherein an area comprising a difference between the substantially transparent region and the second substantially transparent region comprises the touch sensor.
